Be it known thatI, JAMES S. DOYLE, a citizen of. the United States,residing at New York, county. of New York, State of New York, have madea certain new and useful Invention in Metallic Window-Frames for Steel(Bars, of which the following is a This invention relates to frames forsteel ca'rs. r x

The object of'th'e inventionis to provide a metallic window andefficient in operation.

- A further ob ect is to provide a metallic cient receive and guide thewindow sash.

Afurther object is to provide an efiicient and simple construction ofmetallic-window framing for steel cars, in which the'sash are selfadjusting, operate without undue rattle,

Other objects of the invention will appear more fully hereinafter.

The invention. consistssubstantially in the construction, combination,location, and relative arrangement of parts, all as will be more fullyhereinafter set forth, as shown in the accompanying drawing, and finallypointed out inthe appended claims.

Referring to the accompanying drawing,- and to the various views andreference signs appearing thereon,--Figure 1- is 'a broken v1ew, inhorizontal section, of a metallic Window frame for steel oaiis, embodyinthe principleofmy invention. Fig. 2 is a ont' being removed. Fig. 3 is adetail edge view of the s ring employed to take'up wear and to enab ethe sash to adjust itsel and'to be held without noise or ratio in it'sframe.

The advent of the modern steel car, for

to the necessity for new construction for various parts of the equipmentofthe car, in order to meet the requirements of the changed conditionsof the car structure. In the case of the car windows it is found thatthe wooden frames are objectionable for the reason'that they not onlyunnecessarily increase the size and'weight of the car but Specificationof Letters Patent.

they are also not adapted for use in connec Paton-Enos. 10. 1907'.

at withfthe adjacent an we,

moreover, by reasonfot the contraction and '55 expansion of the metalparts of the car framing,the woodenwindowsbecome war causing the sash tobindther'ein, or else t ey become foose, causing an annoying andiimobjectionable noise and'grattle and inducing 0 ra 1d wear anddestructionof. the harness I I wel as the sash. Y I i It is among thespecial-purposes of, presentinvention to avoid the objections" f; noted,and to provideametallicwindow. frame for use in-steel or similar cars,which use in combination and association with the adjacent metal partsof thecarfralni ",and I whereby warping or looseness throng ii -[1pansion .and contraction is avoidedyand wherein the sash are efiicientlyheldfl andj usage to which the operation of street or T other cars aresubjected. I

In carrying out my invention I provide a window frame in the formof' asheet metal plate, preferably shaped into the form of an open sided box.girder, and which, if desired, may form a portion of. the framing of thesteel or other car body. The side. surfaces of this box girder, one orboth, depending upon its position, are suitably shaped to form channelstoreceive metallic channel castings or blocks in whichthe'metallic sidebars of the sash are received,held andguided, a leaf springer bow shapeds ring stripbeing interposed between the ed g to enable the sash to beself adjusting and held and guided without noise, rattle oriundue wear.

Referring to the accompanying drawing '95 A, designates the metallicsheet or plate shaped into the form of a box girder, the sides of whichmaybe shaped into suitable channels and guide beads to accommodate thewindow frame castings and sash and the 'windowvcurtains. In the drawing1' have shown a box girder A, shaped on each of its sides to receive twowindow framechannel castings B, C, and the end of t curtain fixture D.In this respect, however, I do not desire to be limited or restricted asthe cone ofthe sash 90 bar and its receiving channel casting in orderfiguration of'the sides of the box girder may the latter adapted toreceive and form a guide for the shade or curtain fixtures D.

Intermediate the channels E, and F, the sides of the box girdei areformed into a head or rid. e G, against which are received and bear thechannel castings U, which are cooperati'ng-ly'shaped. The edges of thebox girder are formed into flanges H, to which is bolted, riveted orotherwise secured the plate or panel Kn The part L, of the boxgirdcrb'etween adjacent windows may be hush with the-inner Wall ofthorax-and be finished oil in any suitable or desired style ofornamentation. The castings B, are in the form of boxes having anoutwardly presented open side; light strong metal. I have found thatalue minium castings are admirably adapted for my purposes. ihesecastings conform in contour to the shape of the seatsor channels E, andare snugly received therein, the outer side surfaces of said castingslying against the inner surfaces of the edge flanges H, of the boxgirder, said flanges serving to form one side of the seats E. The innercorners of the castingsare inclined to conform to the inclined portionof the surface of the seats E, produced in theformation of the adjacentcads G. The castings C, on the inner edges thereof, are shaped to form aseat for, and to snugly receive, the beads G, of the box girder sides,as clearly shown, the inner side sur. face of the outer casting Blyingand bearing against the outer side surface of the adjacent inner castingC. 'The side bar M, of the outer sash isv preferably of metal and isreceived through the open side of the casting B, which it snugly fits,and in which it is guided in its movements when such sash is raised orlowered. 1

In practice, i prefer to form the side bar M, of strong light metal,such, for instance as aluminium. This side bar, shown, is hollow and isprovided on its outer edge with a seat in which is received the edge ofthe window pane N, a gasket or strip of rubber, felt, or other suitablematerial, indicated at 0, serving as a lining for the pane seat in thesash side bar M. Similarly, the sash side bar P, of the inner sash isreceived and guided within the channel formed in the casting C, and thepane R, of the inner sash is received in a seat formed in the outer edgeof such bar P, and lined with rubber, felt or other suitable material,as shown.

in order to enable the sash to adjust themselves within the channelcastings and to prevent any loosencss and the eonseouent These castingsare preferablyof some noise and rattle, I place a bow shaped or curvedspring strip S. within the castings B, and C, and between the outeredges of the side bars M, and P, and the bottoms ofthe channel castings,as clear] y shown.

The interior of the hollow box girder forms a chamber in which, ifdesired, may be received a sash counterweight, indicated at W. andsuitably connected to the sash. I do not claim this feature herein,however, as the same forms the subject matter of a separate applicationfiled Jan. 29, 1907, Serial No. 354,624.

From the foregoing description it will be seen that I provide anexceedingly simple construction and arrangement of metal window framesfor steel cars, wherein the sash are efficiently held and guided intheir channel castings, and are self adjusting therein, wherein thenoise and rattle incident to the rough usage of cars in service and thewear of such use, are avoided, wherein loosencss or binding due toexpansion or contraction avoided and wherein strength, durability andlightness are most admirably combined. It will also be seen that the boxgirder being a metal plate rolled or bent into the desired shape, may beproduced at very little cost thereby materially reducing the cost ofconstruction of a car. it will also be seen that since the window sashoperate in metallic guidings or channels which are not subject to thewarping ell'cct due to variations in temperature the sash may be readilyand easily moved in their guideways or channels at all times and may beaccurately and neatly fitted thereto without danger of the closeness of.the fit being interfered withv or being destroyed. It will also be seenthat a window embodyin the prii'iciples of my invention affords elicientprotection a ainst the enetration around the' sash o the west 16]., rainsnow or wind, and even under the heavv pressure of a high wind the sashmay stilll be readily and easily operated.

Nhile I have shown and described my invention as applied to steel streetor railway cars, it is obvious that the same is equally well adapted toother structures, as houses, automobiles, ship, boats and the like. I donotdesire, therefore, to be limited or re" 'stricted iii-respect to thesituation in which my invention is to be used.

It is obvious that many variations and changes in the details ofconstruction and arrangement would readily suggest theniselves topersons skilled in the art and still fall within the spirit and scope ofmy invention. 1 do not desire, therefore, to be limits ed orrestrictedto the exact and specific de tails of construction andarrangement shown and described. But

Having now set forth the object and na-' ture of my invention, and aconstruction emas new and useful, and of my own invention, and desire tosecure by Letters Patent is:

1. The combination with awindow-sash,

of a metallic box girder having a'channel formed in the side thereof abox casting fitted to said channel and adapted to receive and guide theside bar of the sash.

2. The combination with the window sash, of a metallic sheet or plate,shaped to form a hollow box girder, and having channels and. beads inthe sides thereof -box castings fitted to said channels and beads andadapted to receive and guide the sash.

3; In a metallic window frame. for steel cars, a metal plate bent toform a box girder,

and having the sidesthereof shaped to form\ and sliding in said. channelcastings and bow springs interposed between said channel casting andsaid sash bars.

6. The combination with a box girder having channel seats and beadsformed in the sides thereof, open sided metallic box castings fittingsaid channels, similar box castings fitted to said beads and sash barsreceived in and guided by said box castings.

7. The combination with a box girder having the sides thereof shaped toform channels and beads, opensided metallic box castings respectivelyfitting in and fitted to said channels and beads, sash bars received inand guided by said box castings, and bow springs fitted between theedges of said sash bars and the bottoms of said box castings.

8. In a metallic window frame forsteel cars, a metal late bent to form abox girder, and having t ie sides thereof shaped to form channel seatsand beads, and terminating in lateral flanges, metal box castings seatedin said channels and bearing against said flanges, other metal boxcastings having their inner edges shaped to conform to and fitting saidbeads, and arranged adjacent to the first mentioned box castings, all ofsaid box castings -preseiii'yt' ing outwardly an open side, hollow metalsashbars received in and guided by said box castings, and each having aseat to receive a Window pane, and a bow spring interposed between theedge of each sash bar and the bottom of its associated box casting.

In testimony whereof Ihave signed my name to this specification, in thepresence of two subscribing witnesses, on this 17th day of January A. D.1907.
